• Signature: public function action_disable()
• Returns: boolean. Returns true on success, returns false on failure and prevents

the module from being disabled.

Perform any actions that a module needs to when it is enabled.

• Signature: public function action_enable()
• Returns: boolean. Returns true on success, returns false on failure and prevents

the module from being enabled.

action_initialize()

Method called before the module is enabled for the first time. @param boolean -- returns true on success. false on error.

• Signature: public function action_initialize()

conflict_external()

Checks to see if a an external conflict is matched

• Signature: public function conflict_external($ext,$req_data)
• Returns: boolean true if the external conflict is NOT met. In other words,

if you have a valid conflict you should return false, otherwise you should return true Parameters:

• string $ext
  The external conflicy
• array $req_data
  The array of conflict data. such as array(0=>array('operator'=>'atLeast','version'=>'3.1'))

getCLIHooks()

Method called to get the modules' hooks which are run from the command line pages

• Signature: static public function getCLIHooks()
• Returns: an associative array where the key is the hookname

and the value is mixed. The first option for the value is that it is a string. This string is the method name to call.
The second option for the value is that it is an array. This array has key 'method' with value the method of the class to call at the indicated hook. It also has key 'proiority' which gives a scheduling priority to the action.
Example we may return: array('pre_page_display'=>array('method'=>'doSomething,'prioriy'=>10), 'post_page_display'=>'array('method'=>doSomethingElse,'priority'=>50), 'post_configure'=>'andNowForSomethingCompletelyDifferent')

Each of the methods takes either 0 or 1 argument depending on the hook. For a complete list of hooks and their arguments see....

getCLIMethods()

Any 'fuzzy' methods that this module implements on the command line.

• Signature: static public function getCLIMethods()
• Returns: an associative array.

the keys are the form of $key = '$class::$method' where $class is the name of a class which is an instance of I2CE_FuzzyMethod and $method is the name of a $method we wish to add to the class $class and which is not already in the class. the value is the name of a public function in the I2CE_Module subclass which will handle the call to $method. Example: array('I2CE_Template->setForm'=>'setForm') You also have the option of array('I2CE_Template->setForm'=>array('method'=>'setForm','priority'=>100) If you wish to set a priority. The default proiority is the priority of the module

and the value is mixed. The first option for the value is that it is a string. This string is the method name to call. The priority for the method in this case is the priority of the module
The second options is is that each value consists of an array with keys integers, the priority, and values the methods
Example we may return: array('post_configure'=>'andNowForSomethingCompletelyDifferent', 'post_junk'=>array( -10=>'method0' 10=>'method1' 100=>'method2' 1004=>'method3' ) )
Each of the methods takes either 0 or 1 argument depending on the hook. For a complete list of hooks and their arguments see....
